Castle Peak Campground offers nine primitive first-come, first-served campsites along Castle Creek in a remote Black Hills canyon setting, ideal for those seeking solitude and a natural creek-side experience.

Access requires traveling 8 miles on rough, narrow Forest Service Road 181 (recommended from the east via Mystic Road rather than the western approach), making high-clearance vehicles essential; sites include fire pits and tables but no potable water.

Peak season costs $19/night with vault toilets available, and the remote location offers no cell service, making it perfect for disconnecting while enjoying creek-side camping.
